Metallic glass fibers

Materials Science Some metallic alloys can be rapidly cooled into a glassy state, which can improve their corrosion and wear-resistance properties while maintaining conductivity. However, such rapid cooling usually limits the size and shape they can assume, and many of the processing methods aren't feasible without losing the glassy state. Yan et al. fabricated meters of uniform fibers with widths ranging from 40 nanometers to a few micrometers by coating metallic glass with a polymer with similar rheological properties. They used the extracted fibers as electrodes in fabrics and combined them with biocompatible polymers that can be used to electrically stimulate and record the activity of neurons. Nat.
